How to Swap to Non-Toxic shower curtain liners:
Here's how to swap to non-toxic shower curtain liners:
What to know about shower curtain liners
Shower curtain liners hang in a warm, humid space where you stand unclothed, often with limited ventilation. That combination of heat, moisture, and proximity to your skin means the materials a liner is made from really matter.
- Most conventional liners are made from PVC (vinyl) or other synthetic plastics that can release volatile compounds, especially when new or exposed to hot steam.
- Because you use your shower daily and the liner is right next to you in an enclosed space, this is a product worth paying attention to.
Check what your current liner is made of
Look at the packaging or product label on your current shower curtain liner to identify the material. The most important thing to check is whether it's made from PVC (vinyl), PEVA, or a natural or safer alternative.
- If the label says "PVC," "vinyl," or "PEVA/EVA," it's a plastic-based liner — PVC is the most concerning, while PEVA is a step up but still synthetic.
- If your liner had a strong plastic smell when you first hung it, that's a sign it may be off-gassing volatile compounds into your bathroom.
Use your current liner more safely
If you're not ready to replace your liner right away, a few simple habits can reduce what you're breathing in during showers. Small ventilation changes make a real difference in a small, steamy bathroom.
- Run your bathroom fan or crack a window during and after every shower to help move air through the space.
- If your liner is brand new, hang it in a well-ventilated area (or outdoors) for a day or two before using it to let initial off-gassing happen away from you.
Choose a cleaner replacement
The best shower curtain liners are made from natural materials like organic cotton, linen, or hemp. If you need a waterproof option, look for one that is free of PVC, PFAS, phthalates, and VOCs, and backed by third-party certifications.
- Look for liners made from natural fibers or, if plastic is needed, non-PVC options that are certified by OEKO-TEX® or GREENGUARD Gold.
